Embodiment Construction

[0022] The spirit of the present invention is to cut slits on only one substrate to create a multi-view effect. A slit is used in a pixel electrode to generate three different voltages of high, medium and low, so that the electric force line is inclined, and the liquid crystal molecules of the same pixel have different inclination angles, thus forming multiple viewing areas.

[0023] Please refer to FIG. 2 , which shows a plan view of a pixel of a multi-view vertical alignment liquid crystal display according to a first embodiment of the present invention. Please also refer to FIG. 3 , which shows a cross-sectional view along line AA in FIG. 2 . The liquid crystal display includes substrates 11a, 11b, a common electrode 12b, a pixel electrode 25, vertical alignment films 14a, 14b and a liquid crystal material filled between the substrates 11a and 11b. The liquid crystal material is negative type, that is, its liquid crystal molecules tend to align vertically to the direction ...

Abstract

A display consists of multiple picture element electrode as these picture element electrodes are used to define multiple picture element which is arranged in array form. Each picture element electrode comprises main, secondary and low electrode as absolute voltage difference value of main electrode to common electrode is maximum, absolute voltage difference value of seconary electrode to common electrode is intermediate and absolute voltage difference value of low electrode to common electrode is minimum.

Description

technical field [0001] The invention relates to a liquid crystal display, and in particular to a multi-view vertical alignment liquid crystal display. Background technique [0002] A Multidomain Vertical Alignment Liquid Crystal Display (MVA LCD) has a characteristic of a wide viewing angle, which can improve the problem that the viewing angle of a general liquid crystal display is too small. FIG. 1 is a cross-sectional view of a conventional multi-view vertical alignment liquid crystal display without voltage application. In FIG. 1, an electrode (electrode) 12a is formed on a substrate (substrate) 11a, a bump (bump) 13a made of insulating material (insulating material) is formed on the electrode 12a, and a vertical alignment film 14a covers the electrode 12a and the electrode 12a. Bump 13a. In addition, the electrode 12b is formed under the substrate 11b, the bump 13b made of insulating material is formed under the electrode 12b, and the vertical alignment film 14b covers...
